Problem with my knock sensor always reading knock. I have a 2000 blazer with a 350 vortec in it and a lt4 hotcam. Ever since the swap I've had a problem with the knock sensor always saying there's a knock. I read where some people moved the sensor from the factory location to where a mechanical fuel pump goes so that's what I did and it cured the problem for a while. I'm on my 4th V8 knock sensor now and the trouble code for the knock sensor (p0327) keeps coming back aftter a while of the installation of a new one. Do I need to desensitize the sensor?

Sometimes a fresh knock sensor harness will fix it, they go out over the years..
Especially if moisture/water ever got in there
